pip is configured with locations that require TLS/SSL, however the ssl module in Python is not avail

sudo apt-get install openssl
sudo apt-get install libssl-dev

查阅资料发现，在./configure过程中，如果没有加上–with-ssl参数时，默认安装的软件涉及到ssl的功能不可用，刚好pip3过程需要ssl模块，而由于没有指定，所以该功能不可用。
解决办法是重新对python3.6进行编译安装，用一下过程来实现编译安装:

cd Python-3.6.5
./configure --with-ssl
make
sudo make install

再次安装问题解决
